I've finished all 4 of the A and P classes and statistics at chamberlain. I'm in week 2 of micro right now. A and P were the hardest for me, especially the first 2 as they focus on anatomy. The second two were a little better, they focused on physiology. They definitely require ALOT of study time but they are possible. I took stats in class and it wasn't too bad, and math is definitely not my favorite. I've heard it's better to take online though. So far I'm loving micro, even though it is a tough one. I think it's really interesting though!
